Great! I just use the front sight to co-witness with my red dot.

This is my 11th set of Magpul MBUS 3 sights, and with Magpul, these are always 100% quality. Regardless of what MCOG you are running, you will always need a quality backup, and the Magpul MBUS 3 is the best there us.

It's a Magpul MBUS - what else is there to say. The standard in backup sights. Third generation is the latest and best of the MBUS backup sights. Polymer, but decent quality. More convenient to operate than the Pro aluminum version.

Really like how compact the gen 3 is. I have a 3x magnifier and wanted to keep some backup sights that could be mounted as far back to the rear as possible and this sight works perfectly. Same great quality that magpul is known for, they work great.

Low profile. Fits nicely under an EOTech multiplier. On my last deployment, my m4 had a fixed front sight, but I’ve seen the mbus front sight on other’s rifles and they all rave about it too! Magpul makes very good products.

The listing failed to specify that the sight is OD Green. Other than that, it is Magpul, you know what you're getting.

These are Magpul and just like other products they make, these are top quality sights. They come in black or dark flat earth colors depending on what you prefer on your setup. The sights are fully adjustable for wind and elevation and are co-witness with scopes or red dots.Mounting was super simple, just need a flathead or phillips screwdriver to loosen and tighten the piece that goes on the picatinny rail. All plastic but very durable. They hold zero after 3000 rounds so far and seem to be able to handle much more. Great replacement for iron sights or in case of emergency while out in the field. Magpul all the way!!
